Question 458716: Essay; show all work. Consider that the age, x, of a unicorn in human
equivalent years can be given by the formula f(x) = - 0.001618x^4 +
0.057326x^3 – 1.1367x^2 + 11.46x + 2.914. When a unicorn is 2.5 years old, what
is its age in human equivalent years? What about when it is 12 years old?

For some reason I have seen this exact problem four or five times the past few months on this site.

To find the human's equivalent age, simply replace all occurrences of "x" with "2.5" and simplify. Do the same with x = 12. For example,



Update: You had asked how to simplify the problem. The best way is simply to evaluate the expression using a calculator. If you have a graphing calculator, perhaps you could enter the function for f(x), then evaluate f(2.5) and f(12).
